College girl Felicity is struggling with biology class. She understands the female reproductive organs because she has them herself but when it comes to the male organs she is lost. She manages to persuade her tutor to strip naked for her and show her how the male genitalia works. Her eyes widen as she sees his dick for the first time and she is amazed at how it becomes erect without him even touching it. When she spreads her legs and shows him her skimpy panties he jerks off until he spunks all over the desk in front of her. Now she understands the male anatomy!
